Chapter 322

In Chapter 325, three days later, Peking University Mathematics and science innovation practice base.

Five mathematical talents from five universities have come together again.

This time Professor Zhong Yongan did not come. In the office, there were only five of them.

"Since Professor Zhong said that the subject was given to us five full powers, we would sit down and discuss some details in detail?" The doctoral guard of Peking University took the lead in opening and laughing.

Among the five, the guards were barely half the hosts, and the rest four nodded and sat on the long table of the meeting in the middle of the office.

I'm afraid the situation is still uncertain about the position of the Lord. No one will go back to sit. So five people sit on both sides of the long table, three at one side and two on the other.

The first project meeting of the joint project of cross school began with such a situation.

Five people can not call each other know each other, perhaps even some people, are yesterday personally met, only know that there is such a number of people. For example Cheno.

In short, the atmosphere on the table was delicate, for a while, no one spoke, looking down at the documents in their hands.

Cough

Finally, the guards could not look at the atmosphere so rigid, so they had to first say, "then, I will say some of my views, it is a brick to start."

He took a document from his hand and his eyes suddenly became serious. "It was a framework of the project structure made by me after I went back to take the document Professor Zhong gave us back to us three days ago and looked at it again

The guardian opened the file and said, "the name of the subject we studied, called the nonlinearity of Darboux transformation of the Kaup Newell equation based on the constrained flow."

"From the perspective of research branch, this is a subject in the field of geometry." The guard smiled, "and the direction I am mainly focused on is geometry, so I still have some opinions on this aspect, and some can listen to it."

The nonlinear method of spectral problems for the (1 + 1) dimensional soliton equation was first proposed by Cao in 1988. According to his account in the "2n dimensional manifold of discrete line spectrum", a continuous linear spectrum problem can be nonlinear to generate a finite dimensional completely integrable Hamilton system... "

Although all the professional contents of geometry are described by the guardian, they are not so deep or remote. The rest four can easily follow his ideas.

The guards have been specialized in geometry since their graduate school, and it has been almost five years since now.

In five years, the guards learned not only some professional knowledge, but also some unique insights accumulated from experience.

“…… For Kaup Newell equation, pt=-12pxx-2 (qp^2) x, qt=-12qxx-2 (pq^2) x Therefore, I think if we use the Backlund transformation which constrains the flow of Kaup Newell equation, we can find that σ n, j = 1D? 1j^d? 2j= ∑ n, j = 1D φ 1j^d φ 2J, thus generating two integrable symplectic maps with different variables! "

The guards spent about five minutes explaining his own views.

Over there, Sheng Fei from Jiangsu and Zhejiang University saw the guards finish, and they could not wait to stand up and hold the hand of the guard. "It is indeed the same as the hero."

Sheng Fei picked up his own folder and smiled, "the thoughts that the guardian students are talking about are almost the same as mine."

"Oh?" So, the guard also came to curiosity, "Sheng classmate, can you show me your."

"No problem." Sheng Fei smiles and gives the documents to the guards.

On the guard seat, he scanned Sheng Fei's documents in two or three minutes, then smiled and gave it back to SHENGFEI. "Sure enough, the framework of the construction of my classmates and Sheng is similar, and the main aspects are basically the same. As for the details, we will really adopt this research idea when we collect the two advantages."

"Three, do you have anything you want to say?" The guards looked at the three men who had not yet spoken to the other side.

Yang Xiao of Jiangzhe University shrugged and smiled, and put his hand at his hand. "I can construct the framework of the project in three days without you. I can't learn this operation. Since both of them have the same ideas, I will not add enough, and I will follow your two project framework directly. "

The only sister of the five people, Igo, also blinked innocent eyes, spit out his tongue, embarrassed to say, "I only had to go out with a friend of Kyoto to play crazy the other day, so However, you are assured that this is definitely the last time. Although you assign me the task, I will do my best to complete the quality and quantity! "

Well, it seems that the girl of Yige is greedy and has not yet taken time to build the framework. Even, I'm afraid that the specific content of this aspect of the project has not been fully understood.

But now none of this matters.After that, I'm glad to hear this.

In this case, Cheng Nuo was the only one who did not ask for personal opinions.

After returning home a few days ago, he inquired about Cheng Nuo with a friend from the Department of mathematics at Tsinghua University. He knew that Cheng Nuo was just a freshman in the Department of mathematics at Tsinghua University.

Although he heard that Cheng Nuo had participated in the research of three subjects, this was not the reason for the guards to put Cheng Nuo on the same level as himself.

In terms of his resume, he has participated in more than ten research projects, large and small, and this year is the first time he has been given the opportunity to participate in cross school cooperation projects.

As for Cheng Nuo, although some dry goods in his stomach were good, the guards would never believe that a freshman could stand on the same level as their four doctoral students.

"What's your opinion, Cheng?" The guard turned to look at Cheng Nuo as a routine and asked with a smile.

He doesn't mind bringing a guy who is rowing. After all, he is an undergraduate, and he is not bad at all.

But, similarly, he did not think that Cheng Nuo would give anything that would make a difference.

"Ah, you ask me?" Cheng Nuo, who seems to be out of his mind, is smart for a moment and asks with a confused face.

This guy It's not like you've been distracted, have you?

The guard thought of it in silence.

He said patiently, "I want to ask if there is any problem with the framework of the topic I just mentioned. If not, we will carry out the research according to that framework. "

The guards changed their words again.

Now he doesn't expect Cheng Nuo, who was just distracted, to say even a little meaningful things. He just hopes Cheng Nuo can give a yes or no answer.

Cheng Nuo said with a smile without hesitation, "Wei Xuechang, the framework you mentioned just now does not have any mistakes."

The guard's face was happy, "then we'll..."

"Oh, wait." Cheng Nuo raised his hand and said with a smile, "I'm sorry, I haven't finished."

"There is no mistake. But, ladies and gentlemen, don't you think this framework is too complicated? " Cheng Nuo smiles.
